Because it contributes to the well-being of the brain, heart, immune system, and more, sustaining healthy progesterone levels is crucial.
Continue reading to learn more about normal progesterone levels and its importance, including the negative side effects of an imbalance.
This table shows the average daily progesterone levels for a woman at varying times during and after her reproductive years. Measurements are taken from blood serum and provided in ng/mL (nanograms/milliliter), and measured levels can fluctuate depending on the type of test taken.
A woman of reproductive age will have daily progesterone levels ranging from 0.1 - 25 ng/mL. Progesterone is lower during the first half of the menstrual cycle and rises during the second half after ovulation, only for the cycle to repeat again if fertilization didn't occur.
Healthy progesterone levels can range between 10 - 290 ng/mL. Progesterone levels will begin to rise steadily starting around the ninth week of pregnancy and will continue increasing until around the 32nd week. Progesterone production switches from the corpus luteum to the placenta around the 12th week.
Daily progesterone levels in postmenopause will usually hover between 0.1 - 1 ng/mL. Since the corpus luteum created from the ruptured follicle after ovulation is the main contributor of progesterone, levels plunge when menstrual cycles end. With treatment, levels can increase to premenopausal numbers.
As aforementioned, the effects of healthy progesterone levels span far beyond the reproductive system. The following are just a few examples of progesterone's contributions to overall health.
Keep in mind that even though many of the aforementioned effects are sectioned into life stages, many occur throughout life no matter one's reproductive stage.

Current progesterone levels are largely dependent of age, current stage of the menstrual cycle, and other factors, such as habits that could be encouraging a state of hormonal imbalance.
Nonetheless, a progesterone imbalance in which levels are abnormally high or low can provoke various negative effects.
Excess progesterone can cause drowsiness, insomnia, headaches, migraines, depression, anxiety, and changes in appetite. Women may also experience vaginal dryness, itchiness, and swelling due a reduction in and thickened vaginal secretions.
Moreover, high progesterone levels can lead to breast tenderness and scantier, longer menstrual periods with abnormal spotting between cycles.
Abnormally high progesterone levels during a pregnancy could signify the presence of a molar pregnancy, which causes abnormal uterine tissue growth due to a genetic error. With a molar pregnancy, the fetus doesn't form properly in the womb, preventing further baby development.
Postmenopausal women who suffer from high progesterone levels may also experience joint pain with accompanied muscle aches.
In addition, with a buildup of progesterone in fatty tissues, hormone receptor sites can eventually stop functioning. This can cause an over-stimulatory effect by estrogen - now unopposed with ineffective progesterone - and adversely affect the heart, inducing heart attack-like symptoms.

Low progesterone levels may lead to ovarian cysts, which are characteristic of polycystic ovarian syndrome (PCOS), with non-proportional estrogen-progesterone levels. Low progesterone can also lead to frequent, heavy periods or an absence of periods.
Likewise, a hormone imbalance may weaken immune and circulatory system functions. In this case, allergies can arise, causing hives, rashes, and other skin conditions.
Low progesterone levels can lead to a condition known as luteal phase defect, in which there is an improper endometrial lining for embryo implantation. This could cause infertility or the loss of an early pregnancy.
Moreover, some women are known to experience mood changes associated with low levels of progesterone post-partum.
Estrogen levels may dominate those of progesterone after menstrual years, causing tender and cystic breasts. Often times, vaginal dryness will also occur alongside abnormal vaginal bleeding. The latter can be triggered by the onset of endometrial cancer.
Additionally, low progesterone levels may be associated with bone loss. And similar to post-partum, low levels of the hormone during the menopausal transition can trigger mood swings and increased anxiety.
